Abstract

La présente invention concerne une technologie permettant de communiquer un ensemble de petites données entre un équipement utilisateur (UE) et un nœud B évolué (eNB). Un état de canal d'un canal en liaison descendante avec l'eNB peut être déterminé au niveau de l'UE. Une indication d'état de canal basée sur l'état du canal peut être communiquée à l'eNB. Les petites données peuvent être transmises à l'eNB au moyen d'une porteuse radio de signalement (SRB) lorsque l'état du canal est supérieur à un seuil choisi.
